Koffie en uw gezondheid*
Uit een langjarige studie onder ruim 145.000 mannen en vrouwen blijkt dat het regelmatig drinken van koffie (tot max. 6 koppen per dag) geen verhoogd risico geeft om eerder dood te gaan. Het blijkt zelfs dat regelmatig koffie drinken in het bijzonder bij vrouwen zelfs een kleinere kans geeft om dood te gaan. Zowel gewone als deca koffie blijkt de kans op doodgaan aan een hartziekte te doen verminderen. Vrouwen die 2-3 koppen per dag dronken bleken in de loop van de studieduur van 24 jaar 25% minder kans te hebben om dood te gaan aan een hartziekte en 18% minder kans op dood gaan in het algemeen dan vrouwen die geen koffie dronken. Bij mannen was er weinig verschil in risico te meten tussen koffiedrinkers of niet koffiedrinkers.
Coffee Drinkers May Live Longer
A new study published in Annals of Internal Medicine has good news for coffee drinkers: Regular coffee drinking (up to 6 cups per day) is not associated with increased deaths in either men or women. In fact, both caffeinated and decaffeinated coffee consumption is associated with a somewhat smaller rate of death from heart disease. 
"Coffee consumption has been linked to various beneficial and detrimental health effects, but data on its relation with death were lacking," says Esther Lopez-Garcia, PhD, the study's lead author. "Coffee consumption was not associated with a higher risk of mortality in middle-aged men and women. The possibility of a modest benefit of coffee consumption on heart disease, cancer, and other causes of death needs to be further investigated." 
Women consuming two to three cups of caffeinated coffee per day had a 25 percent lower risk of death from heart disease during the follow-up period (which lasted from 1980 to 2004 and involved 84,214 women) as compared with non-consumers, and an 18 percent lower risk of death caused by something other than cancer or heart disease as compared with non-consumers during follow-up. For men, this level of consumption was associated with neither a higher nor a lower risk of death during the follow-up period (which lasted from 1986 to 2004 and involved 41,736 men). 
The researchers analyzed data of 84,214 women who had participated in the Nurses' Health Study and 41,736 men who had participated in the Health Professionals Follow-up Study. To be in the current study, participants had to have been free of cancer and heart disease at the start of those larger studies. 
The study participants completed questionnaires every two to four years that included questions about how frequently they drank coffee, other diet habits, smoking, and health conditions. The researchers then compared the frequency of death from any cause, death due to heart disease, and death due to cancer among people with different coffee-drinking habits. 
Among women, 2,368 deaths were due to heart disease, 5,011 were due to cancer, and 3,716 were due to another cause. Among men, 2,049 deaths were due to heart disease, 2,491 were due to cancer, and 2,348 were due to another cause. 
While accounting for other risk factors, such as body size, smoking, diet, and specific diseases, the researchers found that people who drank more coffee were less likely to die during the follow-up period. This was mainly because of lower risk for heart disease deaths among coffee drinkers. 
The researchers found no association between coffee drinking and cancer deaths. These relationships did not seem to be related to caffeine because people who drank decaffeinated coffee also had lower death rates than people who did not drink coffee. 
The editors of Annals of Internal Medicine caution that the design of the study does not make it certain that coffee decreases the chances of dying sooner than expected. Something else about coffee drinkers might be protecting them. And some measurement error in the assessment of coffee consumption is inevitable because estimated consumption came from self-reports. 
The study, "The Relationship of Coffee Consumption with Mortality," was supported by National Institutes of Health research grants. 
Annals of Internal Medicine is one of the most widely cited peer-reviewed medical journals in the world. The journal has been published for 81 years and accepts only 7 percent of the original research studies submitted for publication. Annals of Internal Medicine is published by the American College of Physicians (ACP), the largest medical specialty organization and the second-largest physician group in the United States. 
ACP members include 125,000 internal medicine physicians (internists), related subspecialists, and medical students. Internists specialize in the prevention, detection, and treatment of illness in adults.  (
